Every modern ventilation or air-conditioning system is equipped with one or more diffusers that help distribute the air around the premises evenly. In addition to even distribution, such HVAC supplies enhance mixing of ventilating and conditioning air and feature soundless operation. The following guide will help you know what details to pay attention to in order to select a perfect HVAC diffuser.

First of all, specify the size of your future diffuser. This is a simple step to complete, since the size of a diffuser usually matches the size of duct or application’s outlet where it will be installed. The shape of the diffuser should be taken into account, as well. Of all the round, square, rectangular or linear slot diffusers select the one that will fit your system.

Next factor to consider is the type of installation. There are two main types that are offered at today’s market – ceiling and wall mounted. In order to select the type that will fit your ventilation needs the most, you need to carefully calculate the location where the diffuser will be installed. Here are the most important installation requirements that will help you make the right choice:

A HVAC diffuser has to be installed in a straight section of duct since elbows or kinked ducting lower the air distribution quality and increase noise level;

Try not to place a diffuser after or before other air controlling devices.

When following the instructions from above, selecting the installation type of the diffuser should also be easy. After this, pay attention to the HVAC diffuser's material and durability. Needless to say that it has to be highly resistant to harsh environments, moisture and air pressure. The material that matches all of the requirements and in addition to that provides rigid construction is steel, and its various modifications. Before you buy any HVAC diffuser, ensure it is made from steel.

After all of the factors from the above are taken into account, you can purchase the diffuser that you have selected. However, some of the questions may still require answers and clarification.

What benefits a diffuser has to offer and why do I need to install it?

Would you like to always have fresh air in every room of your house or are you content with the air quality that you have now? If ventilation is not a problem and the conditioned air is evenly distributed through the system, you might not need to install a diffuser after all. But if you have tried everything you could think of and some of the rooms still don’t get enough fresh air, an HVAC diffuser may be your solution.

How much money will I spend to install such item?

If you do it by yourself, the answer is no money at all. However, if you don’t know what tools to use and what location to choose to install a diffuser in the system, you need to hire a certified professional who will take money for his work.
